US tells Russia it won’t rejoin Open Skies arms control pact

The Biden administration informed Russia on Thursday that it will not rejoin a key arms control pact, even as the two sides prepare for a summit next month between their leaders.

Thursday's decision means only one major arms control treaty between the nuclear powers — the New START treaty — will remain in place. Trump had done nothing to extend New START, which would have expired earlier this year, but after taking office, the Biden administration moved quickly to extend it for five years and opened a review into Trump's Open Skies Treaty withdrawal. The officials said that the review had been completed and that Sherman had informed Russian Deputy Foreign Minister Sergei Ryabkov of the U.S. decision not to return to the 1992 Open Skies Treaty. The officials were not authorized to discuss the matter publicly and spoke on condition of anonymity. The State Department later announced the move. "The United States regrets that the Treaty on Open Skies has been undermined by Russia’s violations," the department said. "In concluding its review of the treaty, the United States therefore does not intend to seek to rejoin it, given Russia’s failure to take any actions to return to compliance. Further, Russia’s behavior, including its recent actions with respect to Ukraine, is not that of a partner committed to confidence-building."
